GAMMA-RAY INDUCED BOLD SEEDED MUTANT IN VIGNA MUNGO (L.) HEPPER

Published on

A vigorous and bold seeded mutant was isolated from M2 progeny of 20 kR gamma-ray
irradiated plant population of Vigna mungo cv. T-9. The mutant had larger leaves and
flowers similar to control but upper part of style and stigma of each flower was cu:ved. The
mutant had larger and healthy pods bearing bolder seeds and showed higher seed
yield/plant. Cytologically, it showed normal meiosis. The X2 test showed that the mutation
is controlled by a single recessive gene. The protein content was higher in the mutant while
amino acids and trypsin inhibitor activity were more are less similar to the coritrol.
 

Keywords: Vigna mungo, gamma-rays, genetic nature, amino acids, trypsin inhibitor activity.
